Can you drink water overnight? Can you drink water overnight

You can drink itPlain water is the most drunk water in daily life, although it is light and tasteless, but it has an indispensable position for the conditioning effect. Drinking a glass of warm boiled water on an empty stomach in the morning is beneficial to the body without harm.

The nitrite content in overnight water is twice that of freshly boiled, and nitrite can form carcinogenic nitrosamines in the human body, so overnight boiled water has been circulated as "carcinogenic" water.

The process of boiling water is actually the process of sterilization, and after the water boils, the bacteria and viruses carried in it are close to 0.

There is no scientific evidence that nitrite in water is carcinogenic.

Most of the bacteria contained in boiled water are carried by the container.

Overnight water is drinkable, many people feel that overnight water is not drinkable, they feel that there are many harmful substances in the overnight water, because in the process of overnight water has some chemical reactions, producing more harmful substances, and even carcinogens, so these people dare not drink overnight water. However, scientific studies have shown that after a night of water, if it is pure water, there will not be much chemical reaction, and no harmful substances will be produced. Therefore, the overnight water is drinkable, not only the overnight water is drinkable, even if it is a day, as long as it is well protected and there is no dust, it can be drunk if it falls inside.

Scientific studies have found that even after 2 or 3 days of boiled water, the harmful substances produced in it are very limited.

In general, it is okay to drink water overnight, but try to drink it the next day and avoid overnight again. In addition, there are also requirements for the preservation of overnight water, if it is placed in a cup, kettle and other containers without a lid or with a lot of scale, as well as in a dusty and stuffy environment, it is not recommended for patients to drink it overnight to avoid adverse symptoms such as abdominal pain and diarrhea caused by bacterial growth.

Purified water or boiled purified water is basically inactivated by bacteria, and a short overnight stay does not cause bacteria to grow, so it can be drunk. However, if it is left overnight for a long time and is not sealed and stored, it provides an opportunity and place for bacteria to grow and multiply, and continuing to drink overnight water or boiled water for many times may affect gastrointestinal function, causing abdominal pain, diarrhea and other symptoms.

However, overnight flower tea, green tea, wolfberry water, barley water and sugary drinks are not recommended to be drunk after a long time, mainly because it is easy to breed bacteria, and may also contain nitrite, often drinking a large amount of nitrite poisoning risk, dizziness, fatigue, rapid heartbeat, dyspnea, vomiting, and even coma, convulsions and other serious reactions, affecting physical health.

1. You can drink it.

In fact, boiling water that has been left overnight contains very little nitrite, which means that it will not cause carcinogenic and toxic harm to the body. Although the amount of microorganisms in the boiled water left overnight may increase somewhat, it will not affect the human body.

Not drinking overnight water is a drinking habit for many people. However, two primary school students in Beijing proved through scientific experiments that water can be drunk overnight.

In the science and technology museum, they placed the hot water for one day, two days, three days and the water sample of tap water for comparative chemical analysis, respectively, and measured the pH value, phosphate, nitrate, dissolved oxygen, chlorine, chemical oxygen consumption and other values are within the normal range, that is, overnight water does not have any *** for the human body, and can be drunk.

The two elementary school students did this experiment because they secretly visited some institutions and found that an office of a certain institution made four thermos of boiling water every day, and the next morning they had to pour out more than one bottle. The agency has a total of 62 offices, and 38 tons of water are dumped in a year. How many offices there are in Beijing, and how many offices there are in the country, the amount of water wasted without overnight water alone is a staggering amount.

The two primary school students used science to tell people that water can be drunk overnight, and also put forward specific water-saving suggestions: first, we should be careful and make a careful calculation, drink as much water as we want; The second is to concentrate **, prepare some clean containers to gather the remaining water and then use it for other purposes; The third is to use an electric water heater, and you can drink as much as you want. It should be said that these suggestions are not difficult to achieve.

China is a water-scarce country, but on the other hand, there is a serious waste of water resources. Establishing a sense of water conservation, making effective use of limited water resources, and putting an end to all waste of water resources are major issues that have a direct bearing on the future survival and development of our nation. Shouldn't all the adults do better in the face of the "scientific" advice of two elementary school students?

Hello! Yes, even if it is overnight, the water will not be a problem! It's also drinkable!

Water is the source of life, water plays a very important role in human health, we must pay attention to the way of drinking water and the hygiene of drinking water in daily life. Usually, what people call overnight water is water that is boiled the day before and stored for the next day. Boiled water bacteria are essentially inactive and can be drunk if the overnight water can remain pure during the overnight period.

If you usually have the habit of drinking water in the morning, you can put it in a clean water cup and cover it the night before, pay attention to the hygiene of the water, and do not get contaminated.

Boiled water can be drunk overnight. But overnight, which is 8-12 hours, is no problem. Overnight boiled water contains certain bacteria, but not a lot, and drinking plain water has many benefits for the body.

You can drink it, no problem, but it's best not to drink too much, and it mainly depends on whether the water container is clean.

Overnight water is generally drinkable. The premise is overnight water in a hygienic environment.

Dear, overnight water is drinkable, but overnight tea cannot be drunk.

Overnight water can be drunk if you store it yourself.

When the water is boiled, there are very few bacterial active substances in the water, so the nitrate component is less. However, if you use the cup directly, so that the bacteria in the mouth stay in the water overnight, there will be a risk of bacteria exceeding the standard, and it is recommended to pour out this small glass of water.

Can you drink boiled water overnight.

Many people say that overnight water has a peculiar smell and can no longer be drunk, that is due to the fact that the air contains carbon dioxide, and boiled water is exposed to the air for too long, which will produce some peculiar smells. However, if the water is boiled at high temperature in a clean and tidy environment, 99% of the bacteria can be destroyed, so there is no need to worry about not drinking water overnight.

But if it's a little water in your cup, you should pour it directly the next day, so as not to multiply the bacteria in your mouth in the water overnight and drink it is not good for your health.

In addition, it is important not to drink raw or unboiled water, as it contains a lot of bacteria and chlorine in tap water, and drinking it without boiling it is not good for your health.

Can you drink overnight tea?

Generally, it does not exceed 12 hours, it can be drunk, although the ingredients in the tea soup have changed, but it is not a big problem for the body. Overnight tea tea for more than 12 hours can not be drunk, in addition, the usual overnight water can not be drunk, which refers to this overnight tea water, because the tea at night has been precipitated for a long time and is not fresh.

Although it is not recommended, it has many benefits. Tea leaves soaked overnight contain a lot of essential oils, which can remove bad breath, tea polyphenols are precipitated after a long time of soaking, and are used to compress the eyes and ease redness.

Many people think that overnight water cannot be drunk, and many people think that it can be drunk, but can it be drunk or not?

Can't you drink water overnight? In fact, it can be drunk, because there will not be a large amount of nitrite in the water, and it is still far from exceeding the standard, so it is drinkable.

"Overnight water can't be drunk" is mainly because overnight water contains chemicals such as zero alcohols, oxyphenols, and hydroxyhydrogen, which can cause diarrhea and even produce carcinogens nitrite.

OK. Nitrite in water is not produced in a vacuum, but is generally converted from the original nitrate in the water. There is very little nitrate in qualified drinking water; However, if the water source is contaminated with nitrogenous organic matter, nitrate levels may increase.

The reason for the increase of nitrite caused by repeated heating of drinking water is mainly the increase of nitrite concentration due to water evaporation and concentration, but the total amount does not increase; Another possibility is that some nitrates are heatedly broken down into nitrites. China's sanitary standards for bottled water stipulate that the nitrite content in water shall not exceed 2 micrograms per liter.

Overnight water can be drunk.

Because the production of nitrosamine substances requires a suitable environment and precursor substances, but the bacterial substances in the water will lose their activity after boiling, and the nitrate content is small, and there is no basis for the production of a large number of nitrosamine substances.

Therefore, even if the boiling water is left overnight, it will not change the properties of the water itself, and the microbial content may increase, but it will not cause great harm to the human body.

Overnight water treatment method:

When the water is boiled, it is best to put it in a sealed environment, such as a thermos, so that the water does not come into contact with the air and avoid contamination with bacteria, which can damage the health of the human body.

Therefore, as long as it is treated as above, the water can be drunk overnight. However, even if it is sealed. Do not leave the preserved water for too long, and set the deadline at about three days.

Don't be reluctant, otherwise, you will damage your own health and endanger your life.

It doesn't matter, his harm to the human body is minimal, of course, it is better to drink the boiled water that day.

It's best not to drink, it's okay to drink some if you're really thirsty, in short, drink less.

You can't drink it, it's not good for your body.

Drink less overnight boiled water:

Nitrite can form carcinogenic nitrosamines in the human body. Some experts have found that the nitrite content in boiled water is higher than that in raw water. Moreover, the nitrite content of boiling water that has been boiled for too long or more than 24 hours has been boiled for many times.

After 24 hours of boiling water, the nitrite content is twice that of the first boil. Chinese residents have the habit of drinking boiled water, and it is best to drink it freshly or only drink the boiled water of the day. Also do not drink boiled water that has been boiled for too long.

Drink plenty of boiled water and not raw water. Boiling and boiling water for 3 minutes can evaporate the chlorine and some harmful substances in the water, while maintaining the necessary nutrients for the human body in the water. Drinking raw water is harmful because the chlorine in tap water can interact with the residual organic matter in unboiled water, which increases the risk of bladder cancer and rectal cancer.

Drink fresh, boiled water, not water that has been left out for too long. Fresh boiled water is not only sterile, but also contains more than a dozen minerals needed by the human body. However, if you drink water that has been boiled overnight in an automatic water heater for too long, not only will it not have any minerals, but it may also contain some harmful substances, such as nitrite.

The resulting nitrite poisoning is not uncommon.

Overnight water really can't be drunk, not because of substances like dihydrogen monoxide, but because overnight water has more nitrites.

Overnight water contains a lot of heavy metals, which are carcinogens, and are extremely harmful to the body, so never drink it.

It is best not to drink overnight water.

Because the water is left for too long after boiling, it will also become aging water, and the toxic substances in the aging water will increase with the increase of water storage time. Therefore, it is best to drink the boiled water on the same day, and some experiments have shown that drinking boiled water that is naturally cooled and left for no more than 6 hours is the most beneficial to human health.

It can be drunk, but it is best to store it tightly sealed, such as with a bottle tightening point with a tighter lid.

It's okay to drink water overnight, it's better than no water at all.

But if you can, don't drink it!
